Specification of Letters Patent.

Patented Nov. 30, 1915.

Application filed October 3, 1914. SeriaLNo. 864,771.

To all whom it may concern.

tain new and useful Improvements in Folding Chairs; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to folding chairs of the class wherein the seatand fore legs fold against the back.

My object is to provide a comfortable, strong and durable chair, easy ofoperation and of moderate cost.

In the drawings herewith which are made a part of this applicationFigure l is a side elevation. Fig. 2 is a plan view of the bottom of thechair revealing the locking mechanism. Fig. 3 is a fragmental verticalsectional view on the line 4c4 in Fig. 2. Fig. 1 is a perspective viewof the notch into which the latch moves. Fig. 5 is a plan view of thenotch on the lines 55 of Fig. 4:.

In referring to the drawing in detail, numerals will be used to indicatethe various parts and the same numeral will be used to 5 indicate thesame part throughout the various views there shown.

The chair comprises three principal parts; the rear frai'ne 1, the frontframe 2 and the seat 3, and the means for bracing and holding the partsof the chair in rigid operative relation to each other. These variousparts will be specifically described hereinafter.

The back frame 1 comprises two upright standards of suflicient length toform the rear legs 6 and the back supports 7 integrally, having theusual rungs and cross slats occurring in frame chair construction. Thefront frame 2 comprises two legs 8 of suitable length to support theseat 3 at proper height, being connected adjacent the lower end thereofby an ordinary wooden rung. At the upper end near the extremity thereofthe front legs are connected by a cross piece 9 rectangular in crosssection, positioned so that the widest dimension thereof is presentedfrontwardly and rearwardly. On the top edge of said cross piece, a cappiece 10 is secured, the rear edge thereof being flush with the rearface of the said cross piece, while the front edge extends a shortdistance beyond the front face thereof, the upper face of said cap piecebeing ad acent the top ends of the front legs 8 and a short distancebelow the said top ends. In the said cross piece 9, in its upper edgeand adjacent each end thereof, elongated notches 11 and 11 are out, theinner end 12 of the notch 11 being cut concave. In the lower andrearward part of the notch 11 a portion 13 of the material is left, theend 14 of which is rounded to conform to the concave portion 12. Thesaid portion 13 forms a holding member for the latch hereinafterdescribed. The notch 11 is formed identical with the notch 11.

The seat 3 comprises a square frame hingedly mounted upon the rear frameby strap hinges l5 and furnished with a covering of any preferredmaterial.

Pivotedly connecting the front and rear frames are two metal rungs 16 oneach side of the chair. The said metal rungs, when in normal position,extend parallel to the plane of the seat when said seat is in its normalposition and also parallel to each other. Connecting the two frames aretwo lateral braces, one of said braces comprising a member 17 shapedsubstantially as an elongated U, and two bars 18, the other of saidbraces comprising two bars 19 and a U-shaped body portion 17" similar to17 except that the part connecting the ends there of is shorter thanthat of the member 17 The members 17 and 17 have their ends bent to formeyes 20. The bars 18 and 19 have one end bent to form an eye 21 and theopposite end bent at a right angle to the body portion. The U-shapedmember 17 is secured to the legs of the front frame by means of staples22, the second U-shaped member 17 being secured to the legs of the rearframe in the identical manner as the member 17 is secured to the legs ofthe front frame. The two bars 18 are positioned on the U- shaped member17 by means of the eyes 21, turned on the ends thereof, engaging thecross bar of said U-shaped member adjacent the ends thereof. Each ofsaid bars 18 connects the U-shaped member 17 with a rear leg a shortdistance above the seat 3. The bars 19 are secured to the U-shapedmember 17 in an identical manner and in the same relative positionthereon as the bars 18 are secured to the member 17, the bent portion ofthese bars 19, however, be-

The retainingplates23 and 23 hold in operative position thefbars19- and also the latches 24and 24 The said latchesare 'p1v-- oted to the retaining plates and 23and are provldedwlth'flanges 25 and 25 on the rear edges thereof tobegrasped when operat'ing the latches; Flanges '26 and 26- are provided-onthe" 'frontcdges thereof, said.
